demonstrated the originality and uniqueness of our approach by
achieving successful results with intratesticular administration of
V and V+ASA for castration purposes. The most practical and ideal
agent for castration has been determined as vaseline. Because,
vaseline has been evaluated both the most economical chemical
agent applied up to our time, and no reaction other than local
reactions (edema, discoloration, sebaceous cyst) lasting three to
four days has been observed in animals. In this study, it has been
determined that intratesticular injection of V and V+ASA is a method
that nonโinvasive, most suitable, most economical, most humane,
most practical, widely applicable, and minimally complicated. It is
thought that this technique can be used practically by veterinarians
to provide a permanent solution to the problem of stray animals.
Immunocastration is considered the best alternative technique

androgens, progestagens, anabolic steroids, and antiandrogen
antagonists are used for castration purposes. However, the castration
effect of these hormones is temporary and therefore they need to
be repeated regularly [43]. There are numerous disadvantages to
this repeated regular application: It is not costโeffective to apply

FSH, LH, and Testosterone occurred in Group V, and vaseline alone
could achieve the desired castration effect. Although the castration
effect of Group V+ASA was fully shaped as in Group V, hormone levels
were found to be slightly higher compared to Group V and closer to
